Application filed January 24, 1922. Serial No. 531,388.

To all 'whom it may concern:

Be it known that we, LLOYD A. T. SonnANE and VERLE V. VAN NATTAN, both citizens of the United States, and residents of the city and county of San Francisco, State of California, have invented-new and useful- Improvements in 'Grease Retainers and Dust Caps, of which the followin'g is a specification.

Our invention has for its object means for preventing the escape of grease or other lubricant from the rotating shaft and bearings of a vehicle and at the same time preventing the ingressof dust. It is particularly applicable to the rear construction of an automobile.

Other objects will appear from the draw in s and specifications which follow:

eferring to the'drawing, Fig. 1 is a cross section through the center part of the wheel and bearing 'of the well known Ford automobile, with the rear axle shown in full and with our invention applied thereto. The other parts of the automobile are not shown being well known; I

Fig. 2 is a detail of the cup leather.

Fig. 3 is a front View of the cilp leather of Fig. 4. is the clamp ring. Fig 5 is a full view of the-dust cap. Fig. 6 is a front view of the spring ring.

Fig. 7 is a front view of the jpurn'al retaining ring.

Fig. 8 is a side view of Fig. 6.

Fig. 9 is a second View of Fig. 7.-

Throughout the figures similar numerals refer to identical parts. i The numeral 1 indicates one of the rear axles of'an automobile, as that of-the well known Ford car, on the taper end of which is mounted the hub of the wheel 2 and having clamped thereto'the bushing 3 and the hub cap 4, which latter covers the screw end and' nut 5 of the said axle. The axle 1, is 'adapted to rotate within the roller bearing, one

' of the group of rollers being indicated at 6.

These are 'peripherallyiarranged within the bearing shell whichis rigidly connected to the rear construction of the automobile in any well known way. At 8 is shown a felt washer adapted. to rub against the dust cap 9 when the wheel and hub 2 rotate. It wi]l be seeli'that within the dust cap is mounted the cup leather 10 which clamps against the stationary element 7 the periphmeans to secure said dust cap on said ,cup 110 4 follows:

ery of the dust cap 9 being pressedagain st the external surface of 7 by the clamp ring 11, which latter is drawn up by the screw I and nut 12. It will be seen that the cup leather 10 is formed to cup around and compress against the shaft 1 at .12 by the spring rin 13. This latter is preferably formed wit a continuous annular outer portion 14' having extended inwardly therefrom a series of curved leaves as 15 which form a spring for the purpose of forcing the inner portion of the cup leather 10 against the shaft with a slight compression at 12.

At 16 is shown the journal retaining ring by which the rollers 6 are retained in their proper alignment without interfering with the cup leather 10. v

Referring particularly to the inner part of the cup leather at 13 it wilI be seen that this is cut on an angle so that the shaft in ro-' tatin will more efliciently be wiped by the angu ar positioned edge 13 of the said lever (see Fig.2). v

The manner of-fitting and operating is as The hub cap 4 is first removed, the nut 5 separated from the shaft 1 and the hub 2 pulled clear of the shaft. The journal retaining ring 16 is then inserted against the stationar member 17. The spring ring is next set in place'within the cup leather and the two parts thus'assembled are slip ed over the stationary element 17. The ust cap is then slipped oveixthe outside of the cup leather and the clampiring 11 adjusted and securely fixed by tightening. the screw 12. The wheel and hub with its felt washer 8 are next put in place on the shaft, secured and the hub cap 4 "replaced. The apparatus is now ready for operation.- It will be seen that by our inventiong'rease or-lubricant within the journal and around the roller 6 is preventedfrom getting out by'th'e;wiping effect of the angular edge'13 of the cup loathe er 10;"also by the wiping effect of the belt washer 8' against the dust cap 9 the dust is prevented from getting in and 'contaminat in the lubricant and injuring the parts.

e claim:

1. As an article of manufacture, a cup shaped packing-member formed to fit within a dust cap, a dust cap, an inner project ing collar formed within said member and concentric with the periphery thereof, clamp ion member and to compress the latter a ainst a relatively stationary part of a ve icle, a spring member constructed and adapted to normally compress Said collar, and a bearing retainer ring adapted tocover said spring member. i

2. s an article of manufacture, a cup shaped packing member formed to fit within centric with the periphery thereof, clamp' a dust cap, a dust cap, an inner projecting collar formed within said member and conmeans to secure said dust cap on said cup member and to compress the latter against a relatively stationary part of a vehicle, a spring member constructed and adapted to normally compress said collar, and a bearmg retainer ring adapted to cover said spring member, the inner edge of said collar presenting a wiping edge making an acute angle with the axis of the cup member 3. In combination with a wheel and axleof a vehicle, a cup shaped packing member formed to-fit within a dust cap, a dust cap, an inner projecting collar formed within said member and concentric with the periphery thereof, clamp means to secure said dust cap on said cup member and to compress the latter against a relatively stationary part of a vehicle,- a springmember constructed thereof,

and adapted to normally compress said oollar, and a bearing retainer ring adapted to cover said spring member.

4. In combination with a wheel'and axleof a vehicle, a cup shaped packing member formed to fit within a dust cap, a dust ca an inner projecting collar formed within sald member and concentric with the periphery clamp means to secure said dust cap on said cup member and to compress the latter against a relatively stationary part of a vehicle, a spring member constructed and adapted to normally compress said collar, and a bearing retainer ring adapted to cover said spring member, the inner edge of said collar representing a wlpmg edge; e
